Question

In a monohybrid and a dihybrid cross first filial and second filial generation is observed . Different between F1 and F2 generation by giving three points.

Answer 1

ratio of F1 generation is 3:1 & 1:2:1
ratio of F2 generation is 9:3:3:1 & 1:2:2:4:2:1:2:1

Answer 2

Answer:

There are many differences in monohybrid and dihybrid crosses.

Explanation:

1. monohybrid cross f1 generation phenotype is in 3:1 ratio where as in dihybrid cross it is 9:3:3:1 ratio
2. in monohybrid cross only two characters i.e, parental characters are expressed. In dihybrid cross along with parental characters new features are also observed
3. Monohybrid cross genotype is homozygous where as in dihybrid it is heterozygous
